In 2007, the SEC, like the rest of college football that year, was a complete mess. There were no teams in the entire conference with less than 2 conference losses. Georgia and Tennessee stood atop the East, each with 2 SEC losses, but the Volunteers would represent in the SEC Championship based on multiple close escapes late in the season.
The SEC East in 2011 looks like it could be just as much of a mess with no champion decided until perhaps the very end of the season.
Yes, Georgia already lost to East favorite South Carolina, but if you take a look at the schedules, the race isn't going to be over anytime soon.
South Carolina has likely wins against Vanderbilt and Kentucky at home, but I see them losing at least 2 out of Auburn, at Miss. State, at Tennessee, at Arkansas, and versus Florida.
Florida has to play Alabama and at LSU, not to mention at Auburn and the rest of the SEC East. Once again, it seems likely they would have at least 2 SEC losses as well.
Tennessee is about to go play in the Swamp this weekend, and they have an even tougher West schedule than Florida. They play LSU at home and at Alabama, plus at Arkansas.
And of course Kentucky and Vanderbilt remain Kentucky and Vanderbilt.
Of course it's still possible that South Carolina, Florida, or Tennessee could be way better than they seem and could burn through their tough SEC schedules and remain undefeated in conference, but I wouldn't bet on it. Georgia, meanwhile, has the easiest SEC schedule of them all, with games at Ole Miss, against Miss. State, and the annual rivalry game with Auburn.
Don't be surprised if the SEC East ends up similar to 2007, with each team having at least 2 conference losses, and maybe even with a tiebreaker determining once again which team will play in Atlanta for the conference championship.
